Alopecia areata is an immune-mediated, nonscarring form of hair loss. A new study using human clinical samples and a mouse model demonstrates that CD8αβ+NKG2D+ T effector memory cells mediate alopecia areata in part through Janus kinase (JAK) signaling and that alopecia areata might be treated with JAK inhibitors.
